Because if one swings a can in a circle
and releases it at the exact position, the centrifugal force should carry it directly to the right. But in real life, it does not, it travels tangent to the circle in which it was swinging.

, I’m not exactly sure what you mean, but it’s obvious that you’re talking about the second reference frame since you refer to centrifugal force. However, when you then ask the questionBecause if one swings a can in a circle and releases it at the exact position, the centrifugal force should carry it directly to the right.
, this observation concerns the first reference frame where you’re spinning and there is no centrifugal force. In short, the question mixes up the reference frames.But in real life, it does not, it travels tangent to the circle in which it was swinging.

You see, the can travels tangent to the circle because the force you swing it with is a vector (changes direction in every moment of circulation ofcourse) and because of that force.
It has absolutely nothing to do with centrifugal force because centrifugal force is always neutralised by centripetal force (you know, the centrifugal force pulls out, centripetal in).
As for the very existance of these two forces, they are imaginary; made up to explain, for example, water not spilling out of the bucket when rotating it.
